IMPROVEMENT lN BUFFlNG-WHEELS FOR FINISHING BOOTS AND SHOES.

Specification forming part of" Letters Patent No. 203,265, dated May 7,1878; application filed November 26, 1877.

To all whom it may concern:

Be it known that I, CHARLES C. GREEN, of the city and county ofWorcester, Common wealth of Massachusetts, have invented 'a new anduseful Improvement in Buffing-Wheels for Buffing the Bottoms of Bootsand Shoes, and for other purposes, which improvement is fully set forthin the following specification and accompanying drawings, in which-Figure l is a perspective view of my said improved buffing-wheel placedon arbor C, which is adjusted in standards B B of frame A, to turn inthe bearings. Fig. 2 represents a half-section of the wheel, showing myslotted curve-spring I fastened longitudinally to the inner edge, and mycam-shaft, having hooks G formed on it, adapted to and placed in saidspring. Fig. 3 represents my camshaft and the hooks thereon. Fig. 4represents an end view of said spring.

The object of my invention is to furnish a device by which thesand-paper or emerycloth can be easily and quickly placed around andsecured to or removed from the wheel; and it consists in making a wheelof either wood or metal of two sectional pieces, in one of which agroove or space is made near the edge, extending from end to end. Theslotted curve-spring is fastened to the inner edge of the othersectional piece, as shown in Fig. 2. In this slotted curve-spring I, Iplace my camshaft, with hooks G adapted to and operated in said slottedspring. The sections of the Wheel are brought together and secured withplates L at the ends, leaving a narrow opening, F F. At the rim thereshould be room for the spring to have action in the groove or spacebefore mentioned. The cam shaft is held in position with the plates'L ateach end, which are fastened with bolts or screws. The end 0 of thecam-shaft is squared for a wrench with which to turn it. Pins M and Nare placed one in the cam-shaft and the other in plate L, to set thehooks in position for introducing the ends of the sand-paper oremerycloth into the narrow opening F F.

The wheel may be covered preparatory for the sand-paper in the ordinaryway, with felt cloth or other suitable material.

It will be seen that with this device, by placing the sand-paper oremery-cloth around the cylinder, and tucking the ends into the narrowopening F, then, with the wrench, turning the cam-shaft hooks down, theywill fasten through the ends of the paper or cloth into the slots P, andthus they are together drawn between the spring and cam-shaft, therebyholding the sand-paper securely on the roll, presenting an even surfaceon the outside for buffing or polishin g purposes.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The improved buffing-wheel having the slotted curved spring I, and thecam-shaft, with hooks G adapted to and operated in said slotted spring,substantially as and for the purpose herein shown and described.

CHARLES C. GREEN.
